Ground Works Featured in Trenchless Technology Article
In the July 2016 issue of Trenchless Technology, Ground Works Solutions’ CFO, Aaron Hall, writes about the successful rehabilitation of a box culvert in Pensacola, Florida. In the piece, Aaron discusses the problems created by historic flooding in Escambia County and how Ground Works Solutions was able to lift a box culvert structure by two feet in order to restore its long-term viability.
You can read about the scope of the project and the challenges in the article here.
How City and County Governments Can Work With Property Owners to Prepare for Storm Season
Spring rains are already coming hard and fast. In fact, the first Atlantic tropical storm of 2015 (Ana) hit landfall in South Carolina in May, even though hurricane season does not officially begin until June 1.
During the past week, Texas and Oklahoma have experienced massive and devastating flooding from torrential rains. While the rainfall has put an end to the drought that has plagued Texas for the past five years, the loss of life and damage to personal property, the infrastructure and the environment has devastated the region.
Just as we’ve seen with the flooding in Texas this past week, heavy rainfall can lead to numerous hazards, including flooding and landslides, which puts human lives at risk, causes damage to buildings and our infrastructure, and destroys crops and livestock. In preparation for rainy season, it’s important to understand the risk and damage that high water events can cause and how…
Zero Excavation Inflow & Infiltration Restoration At the Naval Air Station in Pensacola after a High Water Event
Ever since the U.S. purchased Florida from Spain in 1821, the site where the Naval Air Station (NAS) in Pensacola currently stands has provided a base for military operations. In 1826, construction began on the Pensacola Navy Yard and it eventually became one of the “best-equipped naval stations” in the U.S. During this period, the Navy Yard was used for docking and repairing the warships of that period. When the Navy saw the advantages of aviation in combat, Pensacola became an aviation training station in 1914 and the station was built on the side of the old Navy Yard. In 2014, NAS Whiting Field celebrated 71 years in operation and is considered to be the “backbone of the Navy’s flight program” and is still one of the most important Navy bases in the U.S.
Sealing Annular Space in a Sliplined Pipeline
In the United States, billions upon billions of gallons of stormwater are transported through the local sewer systems every day. The pipes that the water travels through have different degrees of structural integrity. Some of the pipes are as small as 8 inches in diameter and some are as large as 120 inches. The storm sewers can be made out of brick, metal, concrete, clay and plastic. As communities grow and these sewer systems age, local governments are forced to incur costs far beyond the material and labor to rehabilitate or expand the pipelines. Government officials must also figure out how to alleviate traffic delays, as well as business interruptions and disruption to neighborhoods, which can add to the cost of repairing the stormwater system.
One of the oldest and most cost effective methods of rehabilitating an existing drainage pipe is called sliplining. With sliplining, a new, smaller “carrier pipe” is installed inside the old, larger “host pipe.” …
Manhole Structure Repair
Transfield Services, a Florida Department of Transportation contractor, contacted URETEK Holdings to seal the joints and stabilize the soil surrounding the structure for a manhole cover that had settled almost 12 inches due to inflow and infiltration.
The project challenges included total pipe to structure joint failure and high water flow in the pipes. Consequently, other methods had failed, but URETEK was up for the challenge.
URETEK’s solution was to inject the URETEK polymer directly through the base of the structure and invert of RCP to seal and stop the soil mitigation.
URETEK’s business development manager, Tommy Russum, started the process by designing injection port quantities and depths in conjunction with the…
